Xiaomi MIX Flip Review: Best Flip Phone for 2024?

The smartphone market, once dominated by monolithic slabs of glass, is undergoing a captivating transformation. Foldable devices, both bookstyle foldable and clamshell flip phones, have emerged as a compelling alternative. Samsung has been at the forefront of this transformation with its Galaxy Z Flip series. Motorola has also left a significant mark with its Razr series, boasting a large and practical outer screen that enhances usability. Now, Xiaomi has made a bold entrance into the foldable arena with its first foldable, the Xiaomi MIX Flip.

Designer: Xiaomi

At a highly anticipated annual speech event in Beijing last month, Xiaomi CEO Lei Jun unveiled the MIX Flip along with its 4th generation of foldable phones, emphasizing the strategic timing behind the company’s foray into the flip phone market. Reflecting on past perceptions, Lei acknowledged a previous skepticism toward flip phones, once dismissing them as merely “pretty for nothing.” In those earlier iterations, compactness often came at the cost of performance and functionality. However, Xiaomi now believes it has cracked the code, poised to deliver a flip phone that is “pretty for everything”. Let’s delve into the details to see if the MIX Flip truly lives up to the hype.

Aesthetics

The stunning 4.01-inch outer screen commands immediate attention, and rightfully so. It houses two individual rear cameras positioned vertically nestled at the top left corner with minimal protrusion. The shiny outer screen and the matt glass back panel create an interesting contrast, while discreet black Xiaomi logo seamlessly blends into the back panel. Upon closing the device, reveals Leica logo and text on its matte hinge.

The Xiaomi MIX Flip comes in four variants: White, Black, Purple, and Xiaomi nylon fiber edition. The White, Black, and Purple variants share the same matte finish. In contrast, the Xiaomi Nylon Fiber edition features a distinctive woven nylon back panel, adding a unique texture to the device’s aesthetic. Overall, the MIX Flip offers a minimal and clean design.

Ergonomics

The Xiaomi Mix Flip boasts a sleek and highly portable form factor. Unfolded, it measures 167.5 x 74.02 x 7.8 mm, with a folded thickness of 15.99 mm, and weighs 192 g. While it’s not the slimmest or lightest flip phone available on the market, its compact size makes it easy to hold and slip into your pocket.

It feels premium in your hand, featuring an “All-around Liquid Quad-Curved Display” for a smooth feel. The robust hinge allows the phone to be positioned at various angles ranging from approximately 45 to 120 degrees, fulfilling its advertised flexibility. Opening and closing the phone feels smooth and satisfying.

The fingerprint scanner on the right side of the device works great, and the matte back panel resists fingerprints and smudges, ensuring a clean appearance. The glossy aluminum alloy frame tends to attract fingerprints, though this is a minor inconvenience.

Performance

The outer screen of the MIX Flip not only captivates with its stunning visuals but also offers exceptional functionality. Sporting a 4.01-inch screen, it boasts a resolution of 1,392 x 1,208 pixels (1.5K resolution), HDR support, and a pixel density of 460ppi. It achieves a peak brightness of 3,000 nits and maintains an overall brightness of 1,600 nits, ensuring clarity even in bright conditions.

The MIX Flip harnesses the full potential of its impressive outer screen. The large area of the outer screen (3.5-inch to be exact), with a 16:9 aspect ratio, accommodates various apps. Xiaomi enhances usability further by integrating widgets on the left side of the 4.01-inch display, positioned above the camera module. You can customize this area with up to 5 widgets such as Weather, Clock, Calendar, Health, Music Player, and Recent Apps, and you can cycle through widgets by swiping up and down.

Out of the box, the outer screen comes pre-loaded with essential apps like Phone, Browser, Camera, Calendar, Calculator, Weather, Music, Recorder, Clock, alongside a couple of other Chinese apps. According to Xiaomi, over 200 of the most popular Chinese apps are optimized for the outer screen. Since the review unit is the Chinese version, it’s expected that not all apps I downloaded are available on the outer screen. For instance, apps such as Slack, Netflix, Google Calendar, and Kindle are not currently supported on the outer screen. Other popular apps like YouTube, Instagram, X, WhatsApp, Google Chrome, Google Maps, Uber, and Spotify can run on the outer screen. Users can enjoy watching YouTube clips horizontally, leveraging the display’s capabilities fully.

The outer screen is swift and responsive, with notable interactivity. It supports a full keyboard that extends from edge to edge when the phone is oriented with the camera module in the upper left corner, enhancing typing comfort. Additionally, the screen supports handwriting input. While this feature is currently limited to Chinese characters, it adds a useful dimension to the typing experience. You can access quick settings and notifications on the outer screen, though they are not customizable.

On the other hand, the inner display measures 6.86 inches with a 2,912 x 1,224 resolution and 1-120Hz LTPO, featuring 460 ppi and a peak brightness of 3,000 nits, mirroring the outer screen’s brightness and vibrancy, with the crease being barely noticeable. It’s less exciting compared to the outer screen, but it gets the job done with minimum fuss.

Xiaomi’s ongoing collaboration with Leica continues on to its flip phone. MIX Flip features a 50MP Leica main camera with a 1/1.55” sensor, an f/1.7 aperture, and OIS. The other camera on its back is a 50MP Leica floating telephoto camera with a 1/.88” sensor, and an f/2.0 aperture. It supports macro photography where you can get up close to the subject with a minimal distance of 9cm (or about 3.5 inches). You can choose between the “Leica Vibrant” and “Leica Authentic” modes in the camera app to tailor the look to your liking.

The main camera consistently delivers impressive results across a variety of shooting conditions. Images exhibit excellent sharpness, detail, and accurate color reproduction. The camera generally handles dynamic range well. However, some highlight details are blown out without HDR enabled. Activating HDR significantly improves dynamic range, preserving details in both shadows and highlights.

The telephoto camera performs well in daylight or at closer tele zoom levels in low-light conditions, with nice preservation of details. The portrait mode offers a range of focal lengths (23mm, 35mm, 50mm, and 75mm). The skin tone is accurate and subject isolation is great with creamy bokeh. There is a 32MP front-facing camera with a 1/3.14” sensor and an f/2.0 aperture, but taking advantage of the outer screen, you are less likely to open up the front-facing camera for any selfies.

The Xiaomi MIX Flip shines in capturing daylight videos. All three cameras (main, telephoto, and selfie) can record up to 4K resolution at 60 fps with ESI, with the main camera pushing the limits further at 8K 24 fps. Video footage is smooth, well-exposed, and has good detail. While the Mix Flip’s image stabilization performs admirably in low-light conditions, the dynamic range can be somewhat limited.

One advantage of the flip phone is the ability to preview and capture photos and videos on the outer screen. It supports up to 2x zoom for taking photos and videos from the outer screen, though portrait mode is limited to 1x zoom. If you switch back to taking photos from the inner screen, it automatically switches to the front-facing camera, which I find a bit annoying.

Under the hood, the MIX Flip is powered by the latest Snapdragon 8 Gen 3 paired with 12GB or 16GB of LPDDRX RAM and storage of options of 256GB, 512GB, or 1TB of UFS 4.0, with virtually expandable RAM. For reference, our review unit was 12GB RAM/512GB storage. It runs HyperOS based on Android 14. Both benchmark results and real-world use performance are great, handling any task with ease. The Xiaomi MIX Flip is equipped with a 3500mm² VC area, but the device tends to get hot during extended photo and video use.

Compact form factors often compromise on battery size, but Xiaomi has impressively fit a 4,780mAh battery into the MIX Flip. It supports 68W wired charging, although it does not include wireless charging capabilities. Addressing another common issue with flip phones, the MIX Flip allows you to make and receive calls without opening the device. Additionally, it supports WiFi 7 for enhanced connectivity.

Sustainability

While flip phones offer certain advantages, durability is a key area where they can face challenges. The device incorporates Xiaomi’s Shield Glass on the outer screen, promising ten times greater drop resistance than conventional glass. Moreover, the phone has undergone rigorous testing, enduring 500,000 folds without compromising its structural integrity. The battery is another highlight, maintaining at least 80% capacity after 16,000 charging cycles. While the absence of an IP rating might be a concern for some, these features collectively contribute to a device that’s built to last.

Value

As the competition in the foldable market heats up, Xiaomi’s entry promises to shake things up, driving further innovation and consumer choice in the smartphone landscape. Priced competitively at 5,999 yuan (approximately $825 USD) for the base 12GB RAM and 256GB storage model, the Mix Flip undercuts the Samsung Galaxy Z Flip 6 by a significant margin. The 12GB RAM and 512GB variant is also more affordable than the Motorola Razr 50 Ultra.

While Xiaomi Bulgaria Country Manager, Nikolay Nankov, revealed that Mix Flip would be available in Bulgaria for 2,600 Bulgarian lev (about $1,450 USD), notably higher than its price in China, the company has yet to officially confirm global availability. Nevertheless, the device’s competitive pricing (at least for the Chinese domestic market), overall performance, and potential for wider release could disrupt the market and intensify competition in the flip phone segment.

Verdict

Xiaomi Mix Flip is a well-rounded flip phone that combines sleek design, premium build, top-notch performance, and great mobile imaging capabilities. It features a large, functional outer screen (though its full potential is yet to be tested due to the review unit being China version), the latest Snapdragon 8 Gen 3 processor, and two 50 MP Leica cameras, with competitive pricing (at least in China). While global availability details remain pending, Mix Flip stands as a serious contender, poised to shake things up and accelerate innovation in the foldable phone space.
